Perry's office said details of the plan, activated Tuesday, wouldn't be released because of security concerns. However, Perry said that, "With the growing threat of violence in Mexico spilling over the border, we have taken important measures to increase the law enforcement presence along the Texas border and have placed additional resources on standby to combat any potential situation."

The plan includes increased surveillance of border activity and increased ground, air and maritime patrols. Additional resources ready for rapid deployment also have been placed on standby. Those resources include Texas Department of Public Safety tactical teams and Trooper Strike Teams, as well as Texas Ranger Recon Teams prepared to deploy based on the threat.
